    Abstract: A resonant structure for a micromechanical device. The resonant structure comprises a beam and at least one mass attached to the beam. The resonant structure is arranged to have a predominantly rotational excitation mode and an excitation plane in which motion of the excited resonant structure predominantly takes place in use, the at least one mass having a geometry such that none of the principal axes of the rotational inertia tensor of the resonant structure are normal to the excitation plane.
